Abstract
The article presents a study on the potential impact of mining effluents on the health of fish and their habitats. Adult pearl dace were caged for 14 days in a freshwater system of northern Ontario, Canada, that receives effluents from two gold mines. Twenty minnows were deployed into sinking cages positioned at a depth of 1.5 meter for 14 days. Fish were caged several meters downstream of Balmer Lake; downstream of Balmer Lake, municipal waste disposal site, and sewage effluent release point and at two reference sites removed from the above listed point sources.
